Just a simple wall mount D-ring for cable management.
The provided STL inner opening is 30mm x 30mm. I have included the Fusion 360 file if you want to change this to a different size. Just update the length and width parameters.
Print in PETG for better durability / flexibility. PLA should work fine as well.
Hope this is useful.
